Substantial increase in capital investments with $25.4 million of sustaining capital in FY 2016 to transform operations, support a growing production profile, and expand mine life. Primary development increased 44% to 5,462 metres while secondary development more than doubled to 4,751 metres compared to FY 2015.

Capital expenditures up 58% to $29.8 million, of which 85% was invested in sustaining capital, financed 100% through operating cash flow demonstrating the sustaining capability of the operations.

Improved cash operating costs ("COC") to $719 per ounce sold, from $755 in FY 2015. Despite the strengthening of the Brazilian Real and restart of development at Pilar, the Company achieved the lower end of 2016 COC guidance range of $700 - $750 per ounce sold.

Working capital improved to $8.9 million as at December 31, 2016, up from $2.0 million at December 31, 2015.
Working capital reflects a substantial increase in cash invested in primary and secondary development, up 44% and 113% respectively, and includes $10.3 million in loans from Brazilian banks which are renewed every six months and are all classified as short-term.

Q4 2016 Consolidated Highlights

Strengthened the balance sheet with the full conversion of $21.5 million of the Senior Secured Convertible Debentures.

Operating cash flow up 25% to $8.5 million after paying approximately $2.9 million in recoverable taxes.

Consolidated gold production of 25,407 ounces, up 10% from 23,169 in Q4/15. Gold sales up 3% to 25,110 ounces.

COC of $735 per ounce sold, up 16% from $631 in Q4 2015, primarily due to an appreciating Brazilian Real compared to the US dollar, and the restart of secondary development at Pilar, now positioned to commence stoping phase.

AISC of $1,098 per ounce sold, up 11%, from $991 in Q4 2015, reflecting higher sustaining capital spending across all three mines to accelerate primary development, exploration drilling, and equipment investments including the rebuild of the paste-fill plant and recommissioning of Mill #3 at Turmalina.

Established a $10.0 million secured loan facility with Sprott Private Resource Lending (Collector) LP ("Sprott Lending") to fund $8.0 million in accelerated growth exploration commenced in 2017 at all operating mines.

Entered into an arrangement with Avanco Resources Limited to develop and acquire up to 100% of the Gurupi Project through an Earn-In Agreement and NSR Royalty; while retaining exposure to full exploration upside of the property.

Rodney Lamond, President and Chief Executive Officer of Jaguar, commented,"2016 was a successful and transformational year for Jaguar Mining. We exceeded 2016 production guidance and improved cash operating costs to $719 per ounce sold, despite operating under a strengthening Brazilian foreign currency. Operating cash flow increased 56% to $37.8 million while free cash flow turned positive with $11.3 million generated during 2016. Capital investment across all operating mines significantly increased and the projects undertaken in 2016 were fully funded through operating cash flow. During the fourth quarter, Jaguar completed the conversion of all senior secured debentures to common shares which strengthened the balance sheet and our capital structure. Our ability to access capital enabled us to negotiate a $10.0 million secured loan facility with Sprott Lending. Up to $8.0 million of the facility will be used to fund an accelerated growth exploration program in 2017. Additionally, we entered into an arrangement with Avanco Resources Limited to advance the development of Gurupi while retaining Jaguar’s exposure to the significant upside potential of the property."

"In 2017, we expect our gold production to increase to between 100,000 - 110,000 ounces. We are also focused on delivering lower unit costs through the formalization of company-wide expense controls, leveraging technology, and efficiency and productivity improvements from operational excellence programs at both Turmalina and Pilar. Consolidated cash operating costs are expected to be between $720 - $755 per ounce sold and AISC of $900 - $1,000 per ounce sold."

Mr. Lamond concluded: "Sustaining exploration drilling programs completed during 2016 were designed to grow and replace the mining depletion of mineral reserves at our core mining assets and to extend mine life. For 2017, we are confident that our growth exploration drilling programs will provide additional resource growth opportunities. Our team is reviewing and evaluating efforts to achieve the Company’s strategic goal to increase production by 50% by adding back capacity from the Paciência mining complex. This asset was previously placed on care and maintenance in 2012. At our core assets, we are maintaining the increased pace of mine development and accelerated exploration programs to continue to build confidence in current geological models and mine plans. This focus will enable us to achieve our 2017 production guidance with an expected increase in production during the second half of 2017. We are confident and motivated on executing our five-year strategy of increasing the sustainable gold production profile to approximately 200,000 ounces per year."

FY 2016 and Q4 2016 Key Financial Statement Highlights

Revenue for Q4 2016 increased 13% to $30.3 million, compared with $26.8 million in Q4 2015, due to a 10% year-over-year increase in the average realized gold price to $1,205 in Q4 2016 compared with $1,098 in Q4 2015, and a 3% increase in ounces sold. Revenue for FY 2016 also increased 13% to $120.5 million from $106.5 million in FY 2015.

Net loss for the year ended December 31, 2016 was mainly a result of the change in the fair value of the convertible debentures (non-cash loss of $78.0 million) based on the significant increase in Jaguar’s share price from December 31, 2015 to the respective conversion dates of the debentures, which was partially offset by a decrease in the Company’s labour litigation provision amounting to $6.6 million primarily due to a change in the estimate in the first quarter of 2016.

Adjusted EBITDA for Q4 2016 was $6.3 million compared to $7.4 million for Q4 2015, while adjusted EBITDA for the year ended December 31, 2016 was $36.6 million compared to $21.4 million in FY 2015.

Operating cash flow (excluding cash tax refunds) was $8.5 million for Q4 2016, compared to $6.5 million in Q4 2015. For FY 2016, operating cash flow (excluding cash tax refunds) was $36.8 million compared to $16.6 million for FY 2015.

Free cash flow was $2.3 million for Q4 2016 and $11.3 million for FY 2016 based on operating cash flow (excluding cash tax refunds) less total capital expenditures, compared to $0.9 million and negative $1.6 million in Q4 2015 and FY 2015, respectively. Free cash flow per ounce sold was $117 in FY 2016 compared to negative $7 in FY 2015.

Outlook

The following is the Company’s production and cost guidance for 2017:

1Cash operating costs and all-in sustaining costs are non-gaap financial performance measures with no standard definition under IFRS. Refer to the Non-IFRS Financial Performance Measures section of the MD&A. 2017 cost guidance has been prepared on the basis of a foreign exchange ratio of 3.5 Brazilian Reias vs. the US dollar.

2017 Key Growth Drivers

Completing 2017 capital investment program to increase the number of available working areas through increased development and exploration to grow sustainable production across all operating mines.

$8.0 million to be spent on major growth exploration program including Turmalina and Pilar, as well as the high priority Pacheca and Cubas targets near Pilar and other advanced targets. Approximately $6.0 million will be allocated towards Jaguar’s core assets, Turmalina and Pilar, to drive increased mine life. The remaining $2.0 million will be distributed towards other growth targets.

This growth exploration program is primarily focused on increasing identified mineral resources at core assets and the discovery of new resources near existing infrastructure across operating mines. The growth exploration program is expected to complete approximately 31,000 metres of diamond drilling, including approximately 15,000 metres of drilling down-plunge continuities of Orebodies A and C at Turmalina and Orebodies BFII and BF at Pilar. Lastly, approximately 8,500 metres of surface diamond drilling will test the Pacheca and Cubas targets and other advanced targets.

Jaguar has been impacted from the strengthening in the Brazilian Real exchange rate relative to the US dollar, which has had the effect of increasing cash costs in US dollar terms.

The average exchange rate during Q4 2016 was R$3.30 per US dollar compared to R$3.84 per US dollar in Q4 2015. The closing exchange rate as at December 31, 2016 was R$3.26 per US dollar compared to R$3.90 per US dollar as at December 31, 2015, representing a 16% appreciation of the Brazilian Real relative to the US dollar during 2016.

Convertible Debentures

On October 5, 2016, the Company issued a notice of redemption to holders of the outstanding debentures. As set out in the notice of redemption, the outstanding debentures were to be redeemed as of November 8, 2016 (the "Redemption Date") upon payment of 120% of the principal amount and all accrued and unpaid interest to but excluding the Redemption Date.

During Q3 and Q4 2016, all the convertible debentures holders elected to voluntarily convert their debentures into common shares of the Company. The Company has significantly strengthened its balance sheet with the elimination of its senior secured debt.

Liquidity and Use of Funds

Cash balance as at December 31, 2016 was $26.3 million compared to a cash balance of $15.3 million as at December 31, 2015, while investing in capital activities and maintaining a stable working capital position.

Capital investments during 2016 were 100% funded through operating cash flows. In addition to the increase in capital expenditures, Jaguar also paid $1.9 million in other debt principal and interest payments during the year.

Working capital was $8.9 million as at December 31, 2016 compared to $2.0 million as at December 31, 2015, including increased capital spending including annual increases of 44% in primary development and 113% in secondary development.

2016 Actual Performance Compared with 2016 Guidance

The Company exceeded 2016 annual production guidance based on consolidated production of 96,609 ounces. The Company also achieved the lower end of consolidated cash operating cost guidance of $700 to $750 per ounce sold, with cash operating costs of $719 per ounce sold for FY 2016. Consolidated AISC of $1,099 per ounce sold was higher than 2016 guidance due to increased sustaining capital expenditures of $25.4 million for 2016, which represented a 47% increase over FY 2015.

1Cash operating costs and all-in sustaining costs are non-gaap financial performance measures with no standard definition under IFRS. Refer to the Non-IFRS Financial Performance Measures section of the MD&A.

The Company completed 9,914 metres of definition, infill, and exploration drilling during Q4 2016 (Q4 2015 - 6,760 metres) focused on key targets at Turmalina and Caeté, for a total of 37,860 metres of drilling in FY 2016, a 4% increase over 36,240 metres in FY 2015.

The Iron Quadrangle

The Iron Quadrangle has been an area of mineral exploration for centuries, dating back to the 16th century. The discovery in 1699-1701 of black gold contaminated with iron and platinum-group metals in the southeastern corner of the Iron Quadrangle gave rise to the name of the town Ouro Preto (Black Gold). The Iron Quadrangle contains world-class multi-million-ounce gold deposits such as Morro Velho, Cuiabá and São Bento. Jaguar holds the second largest gold land position in the Iron Quadrangle with just over 25,000 hectares.

Non-IFRS Measures

This news release provides certain financial measures that do not have a standardized meaning prescribed by IFRS. Readers are cautioned to review the above stated footnotes where the Company expanded on its use of non-IFRS measures.

Cash operating costs and cash operating costs per ounce sold are non-IFRS measures. In the gold mining industry, cash operating costs and cash operating costs per ounce are common performance measures but do not have any standardized meaning. Cash operating costs are derived from amounts included in the consolidated statements of comprehensive income (loss) and include mine-site operating costs such as mining, processing and administration as well as royalty expenses, but exclude depreciation, depletion, share-based payment expenses, and reclamation costs. Cash operating costs per ounce are based on ounces sold and are calculated by dividing cash operating costs by commercial gold ounces sold. The Company discloses cash operating costs and cash operating costs per ounce as it believes those measures provide valuable assistance to investors and analysts in evaluating the Company's operational performance and ability to generate cash flow. The most directly comparable measure prepared in accordance with IFRS is total production costs. A reconciliation of cash operating costs per ounce to total production costs for the most recent reporting period, the quarter ended December 31, 2016 is set out in the Company's fourth quarter 2016 MD&A filed on SEDAR at www.sedar.com.

All-in sustaining costs per ounce is a non-IFRS measure. This measure is intended to assist readers in evaluating the total costs of producing gold from current operations. While there is no standardized meaning across the industry for this measure, except for non-cash items the Company's definition conforms to the all-in sustaining cost definition as set out by the World Gold Council in its guidance note dated June 27, 2013. The Company defines all-in sustaining costs as the sum of production costs, sustaining capital (capital required to maintain current operations at existing levels), corporate general and administrative expenses, and in-mine exploration expenses. All-in sustaining costs excludes growth capital, reclamation cost accretion related to current operations, interest and other financing costs, and taxes. A reconciliation of all-in sustaining cost to total production costs for the most recent reporting period, the quarter ended December 31, 2016 is set out in the Company's fourth quarter 2016 MD&A filed on SEDAR at www.sedar.com.
